Hello Im upgrading some ventilation systems as the old PLC are dying. (Old TREND IQ series) Since TREND has been used they have also used TREND TE/TI thermistor for measuring the temperatures in the ducts, rooms etc. This thermistor is not linear and info for compability char can be found here https://www.sontay.com/media/specs/Thermistor_Types_and_Compatibility_Charts.pdf Here is also the data on the new equivalent type (TE series discontinued) https://partners.trendcontrols.com/trendproducts/cd/en/pdf/en-ta200724-uk0yr0913.pdf Ive attached a file showing how awful the linearisation is. It ranges from -20c/96974Ohm to 110C/510.1Ohm So my question is, which 6ES7 331- module would be best suited to handle this, and what blocks could i use to remedy the linearisation.
